Lens optics are constructed with one ED glass and four aspherical lens
By combining a large-aperture aspherical lens
and the newly developed focus/zoom system.
This high image quality is made possible thanks to its advanced optical design featuring four aspherical lens
elements, two of which are high precision AA (advanced aspherical) lenses.
The authors described significantly higher contrast sensitivity and decreased aberrations in the aspherical lens
The glass is ground and polished to create an aspherical lens
. This specific shape and surface are complex, but optimal for optics.
three aspherical lens
elements and two ED lens elements.
It uses Sony CMOS sensor and seven-element aspherical lens
The lens unit was realized with HOYA's technology in glass lens molding for aspherical lens
, and optical design and manufacturing for compact camera lens unit.
The aspherical lens
adopted to enhance the lens' focus is made of high -- transmission, low -- dispersion materials and features a nano -- scale, anti -- reflection coating.
The housing is a rugged, lightweight magnesium alloy, and the aspherical lens
is treated with DiamondCoat for superior scratch resistance and provides a wide field of view and excellent image quality--with unlimited eye relief.
doubles the intensity of the received laser reflection.
